I am installing the hella  xl lights on my van, and I purchased the VW
fog light switch to use instead of the rocker switch that came with the
kit.

Now for my dilemma.  The switch came in 3 pieces, a rocker switch, a
bulb socket, and a bulb.  Do I have to take the switch apart to insert
the socket, or how does the socket fit into the switch?

Any help will be appreciated.

Thanks

Ralph
